Values for sterols are given as relative (mean percentages of the total sterol pool ± S.D.) and absolute concentrations (μg mgC-1± S.D., values in parenthesis; N = 4–5); Neutral lipids are provided as percentages of the total neutral lipid fraction; -: not detected.

Table 11. Non-linear regression parameters calculated for the cumulative egg production (y) versus experimental time (x) (see chapter 5, Fig. 2 for fitting curves). Same letters indicate similar cumulative egg numbers when protist prey treatments are compared to the treatments with C. phaseolus and the control without prey (Dunnett’s t-test).
